Alright, so thus far we had a large crowd with some dancing, a cookout, and a statue. Neither was particularly egregious, except maybe the statue, but thus far it wasn't that abnormal for a large crowd of people.
So one could reasonably ask, what exactly was Lumi so surprised about? For the most part, it wasn't entirely surprising, but it was disappointing. As much as he wanted the players to act better, it would take work.
There wasn't exactly any individual action that was catastrophic. It was all the little problems added together that made this an issue.
If one thought the previously mentioned was an issue, then one has not looked very closely. Even while up in the air, Lumi could hear their conversations.
Two players talking might not seem particularly strange until you realized they were players. What would they talk about?
They couldn't discuss the system out loud near natives. So seriously, what would they talk about?
